2 The foregoing Vconstruction generally outlined .isfcanventional' andis adapted particularly for usefyvithmy iin/ention asnow to bedescribed. i' IAs was ,previously stated, the front Wheels v'I .5areconnected Vto the axle 9 so as to rotate there- Afyi/ith.Intermediate the ends of the axle 9 to which the Wheels I are fastened around cam or k eccgantria generally designated I4, is provided suitablyfastenedto the axle 9 by means of the 10 yangles I 5 ateachside thereof.The angles I5 are connected to the round cam member i6 by means of 'anysuitable bolts and nuts il and are in addition xed to the axle by meansof yspot Welding, as V.indicated at I8. lIt will be apparent that the l5rotation of the Vaxle 9 will carry the cam memy'ber It therewith.v ThecamA member I6 is provided with 4guide iianges I9 at opposite sidesthereofjasyindicated in Figure 4.

',Apush rod, generally designated 20 is suitably'mounted in a bearing 2lfastened to the iront of the seat member I. The bearing or guide 2| isof preferably elongated construction so Yas to maintain the push rod 2liin position during'fits movement, as Will be hereinafter vset The pushrod .unit .Zmay preferably comprise a hollow tube 22 andis vprovidedwith a roller .523 ,at the ,lower fend thereof, mounted in a bi--furcated Aportion as shown in Figures 3 and 4. The roller 23 issupported for rotation on a pin Y:.24 vextending through said roller andsuitably `fastened .at opposite sides on the bifureated porv.tion of thepush l'rxod tube 22. The roller 23 is Vadapted to engage' the`peripheryof the cam member IBandisguided in its movement by Vmeans of theiiangesI9 at opposite sides of the ,said cam member I6, as will be apparent.The roller 12.3 is niaintained in contact with the .peripheryof the cammember I6 by means of a ,suitable .springf25l The spring 25 is seated at,itspppeifenduaround the guide 2l and against the under I'side of theseat member l. The opposite dof the v,spring engages a cross pin 25...mounted in position by cotter pins 2l, the said .,vcrosspin` .26`being of sumcient length so as to .engageithe coilslof the spring` asshown in Fig- VIt.lyvilhbe.apparent' that rotation Aof the frontwheelsf'l andqthecam unit I connected to the axle 9 Will'eilect anup'and`dovvn movement of rthe. gure 2B o asftocausethe same to rise and2to.gana.andmamariatheimerest of the child who is riding in thestroller. It will also be apparent that other gures may be substitutedfor that of the horse 28 and the movement thereof in accordance withforward movement of the stroller as a whole, will attract the child.

In view of the foregoing it will be apparent that I have described asimple and yet novel form of baby stroller which includes an animatedfigure therein, and novel means for effecting the animation of suchfigure.

It will be noted that the frame or strap member 8 which supports thefront axle 9 is constructed in a novel manner to afford rigidity of thefront wheel mounting and function as a guard for the axle and cam meanslll. To this end the frame member 3 is secured to the seat l and extendsdownwardly therefrom, adjacent Yone front wheel to a point below theaxle 9,

thence extends transversely of the vehicle directly beneath the axle toa point adjacent the other front wheel and thence extends upwardly to apoint of securement to the seat member.

The portion of frame 8..extending transversely rigidies the upwardlyextending portions through which the axle EB extends and serves toprovide a guard below the axle and cam ill protecting the same.

The brace member i3 further rigidiiies the front wheel mounting,extending` downwardly and forwardly from the seat member to connectionwith the frame member 8 just beneath the cam ld, and thence extendingupwardly and forwardly beyond the frame member to provide the guardportion i3d serving to protect the cam member.

A guide rod 32, connected to the figure 28 and extending through anaperture in the seat i forming a bearing for said rod, assists inmaintaining longitudinal alignment of the gure 28 longitudinally of thevehicle during up and down movement of the figure 28.

Having thus described my invention, what claim as new and desire tosecure by Letters Patent of the United States is:

1. 1n a baby stroller of the class described, in combination, a seatmember, front and rear supporting wheels connected thereto, an axlecarrying a pair of the front supporting wheels and movable therewith, anelongated hollow bearing member extending through the seat member, apush rod mounted in said bearing member for upward and downward movementrelative to said seat, a gure supported on the upper end of said pushrod, a cam member carried by said axle, and a roller member carried atthe lower end of said push rod in engagement with said cam member forcausing said movement of the push rod upon rotation of said axle, anabutment member at the lower end of said push rod, and a coil springencircling the portion of said bearing member extending below said seatmember, the upper end of the spring engaging the seat and the lower endof the spring engaging said abutment to urge the push rod downwardly formaintaining engagement of the roller with said cam, and a frame membersupporting said axle, said frame member being secured to said seatmember and extending -downwardly therefrom, adjacent one front wheel, toa point below said axle and the cam member thereon, thence extendingtransversely of the vehicle directly below the axle and said cam memberto a point adjacent the other front wheel, and thence extending upwardlyto point of securement to said seat member, and a brace member securedto the seat member intermediate the front and rear thereof midwaybetween opposite sides thereof and extending downwardly and forwardlytherefrom and secured to the transversely extending portion of saidframe member midway between opposite sides thereof, and thence extendingupwardly and forwardly therefrom in front of the cam member to provide aguard portion for said cam member.

2. In arbaby stroller of the class described, in combination, a seatmember, front and rear supporting wheels connected thereto, an axlecarrying a pair of the front supporting wheels and movable therewith, anelongated hollow bearing member extending through the seat member, apush rod mounted in said bearing member for upward and downward movementrelative to said seat, a figure supported on the upper end of said pushrod, a cam member carried by said axle, and a roller member carried atthe lower end of said push rod in engagement with said cam member forcausing said movenient of the push rod upon rotation of said axle, anabutment member at the lower end of said push rod, and a coil springencircling the portion of said bearing member extending below said seatmember, the upper end of the spring engaging the seat and the lower endof the spring engaging said abutment to urge the push rod downwardly formaintaining engagement of the roller with said cam and a guide rodconnected to said figure and extending through an aperture in said seatfor guiding the figure in its upward and downward movement.

3. In a baby stroller of the class described, in combination, a seatmember, front and rear supporting wheels connected thereto, an axlecarrying a pair of the front supporting wheels and movable therewith, anelongated hollow bearing member extending through the seat member, apush rod mounted in said bearing member for upward and downward movementrelative to said seat, a figure supported on the upper end of said pushrod, a cam member carried by said axle, and a roller member carried atthe lower end of said push rod in engagement with said cam member forcausing said movement of the push rod upon rotation of said axle, anabutment member at the lower end of said push rod, and a coil springencircling the portion of said bearing member extending below said seatmember, the upper end of the spring engaging the seat and the lower endof the spring engaging said abutment to urge the push rod downwardly formaintaining engagement of the roller with said cam the lower end of thepush rod being provided with bifurcated portions between which theroller is rotatably mounted, said cam member being provided with guidemeans at opposite sides thereof, said guide means being spaced toreceive the roller member therebetween whereby to prevent rotation ofthe tubular member in its upward and downward movement thereof.
